After applying Frontline our cat suddenly behaved strangely as though she was having a fit

Our cat reacted after being treated with Frontline. Looked like she was having a stroke or seizure but recovered . Very worrying while it lasted.

Cariza24 Apr 2017Reply

May I know how long did the symptoms last? My dog is not in coma or stroke andI don't know what to do. He is not moving. I applied the frontline 5 days ago.

Jenn24 Apr 2017Reply

Oh no :( any update? Was your dog ok???
I just applied my 5 month old kitten with her first frontline. She was more sleep after but what really got me is she had a bout of intense yowling 2 hours after that was way louder than normal. She went to lay on the ground and seemed the neck area where I applied FL may be irritated .

Which is why I'm here fuz I wanted to figure out possible side effects to look out for. Never thought of that with a flea meds since I've never seen different behavior after

Applied Frontline to my cat 2 days ago. She started acting crazy, staring at objects with her head tilted. Now she’s shaking her head like she’s having a seizure. I do not recommend this product.

Frontline is crap, I have treated my dog and cats as I do monthly all of them still have fleas and scratch more then they did before. Also my dog now seems to struggle to jump with his back legs and can no longer get on the sofa or bed.

Kelly12 Jul 2017Reply

I applied Frontline Gold on my dog a week ago and he avoids jumping up on the bed or the couch also. He always has jumped up into my lap every time I sit down on the couch and he has not done that or attempted to since I put that on him. I bathed him after the 3rd day of applying it because I noticed his inability to jump up on things and he is scratching more than usual. It's been 4 days since I bathed him and he is still acting like this.

I use to use Frontline Plus on my cat, but yesterday vet gave me frontline gold. Anyway was in the vet office for 2 hours this morning, as my usually noisy up at 5 AM cat, was hiding under the bed this morning and had vomited during the night. After almost $400 of fluids, anti nausea, and blood panel, she is still not meowing, eating or moving around much. Not applying this stuff ever again.

Mt cat almost died 24 hours after the first application of Frontline Gold. It has some additional chemicals in it that Frontline Plus does not that are extremely toxic. After numerous vet visits and a week or so, the cat pulled thru. He is back to Frontline Plus with no problems.

How long after treatment will adverse reaction symptoms appear? I treated my cat who is 12 years old one week ago with Frontline Gold and today she is acting like her back end is out of whack and can hardly walk.

Jo23 Aug 2017Reply

I gave my 20 year old cat Frontline after reading the instructions and telling my vet I was doing it. On both occasions he has gone off his food and had diarrhoea which ARE on the list of side effects, but he goes blind for 24 hours about 48 hours after application... this was certainly NOT on the list. It's very scary and distressing but does not last .... be warned everyone!!!

I'm on here for that reason. My boys 19 and gas gone blind 😭😭😭around 48 hours since administration too! 🙏🙏🙏He will gd ok

Call me crazy, but my pets have successively became me I’ll and have a weird eye thing almost exactly one month after using frontline naturals for cats and frontline plus for dogs (cats both have lethargy, and pulled up inner eye lids, bad gas and really grumpy. One is 6-outdoor mostly, one is only 6 months-indoor only. My boxer now had a really irritated eye, possibly from kitten, but also see a hazy spot in eye). we had many skunks around so we had an influx of fleas. I have found eucalyptus they hate. Hate fleas, hate this product, and any like it. Zodiac is pure death.

מרי, הגשתי את Frontline למכונית שלי לפני שלושה ימים - יש לה את אותם תסמינים. עייף, עפעף פנימי מחוץ לאק. כמה זמן זה נמשך עם החתול שלך?

I used a small amount of advantage for cats 1.5 lbs on my 3 lb cat that I had split between all 3 of them about a month ago however she still had issues with fleas so even tho i still had a week of so to go b4 it had been a month I went ahead and applied about the same amount of frontline on her (again splitting it between them) a couple days later I started noticing a terrible rotten egg smell and finally figured out it was coming from her shes passing gas and it is the worst thing ever. Shes been doing it now for 3 days and I have an appt for her fri to take her to the vet but I was wondering if ur cat smelled of rotten eggs like this when u mentioned the bad gas or if anyone else has experienced this?

Mel22 Jan 2018Reply

My dog also is reluctant to jump up on my bed or into the car since using frontline plus. She’s very lethargic too. This is very worrying to see other cases. Can you tell me if your dogs recovered ok and how long it took

Cariza22 Jan 2018Reply

My dog is having the same symptom as your dog but now it's getting worser. I don't even know what to do. He seems like stroke. He keeps moaning when I called his name. He is in bed rest. I hope that someone will reply if there dogs recovered from this. Your reply will serve as strength. thank you

Yes my dog still doesn’t seem to have improved. Buy fairy dishwashing liquid from the supermarket and keep washing your dog in that. It’s a degreaser and should get it out of its oil glands. Good luck and let me know how you go

Yes I’m pleased to say the fairy dishwashing liquid worked wonders. I washed her a couple of times and she’s happily back to normal. I was so scared she was going to die. I used to use frontline plus on my other dogs but never again will I use it after what it’s done to my latest dog. Good luck

I applied Frontline on my dog 13lbs a month ago. I have had him to two different vet's in last two weeks. They can't find anything causing his situation most all the Symptoms as everyone else. Fustrated and it was time to reapply the Frontline. It dawned on me to look up and find what you all are talking about. Being real sure this is what is going on with my dog. Called the vet. And they say doubtful. I don't understand why the stand up for it. I know it is the problem. He is a little better today. And when he is outside his symptoms seem gone. He chases rabbits full speed. But as soon as he comes in. All the Symptoms reappear. Strange.
Battery eyes, shaking, loss of appetite,letharic, ect.
I need to find a vet willing to accept the diagnosis and somehow treet.
Has anyone been successful with it clearing up?

Hi David
I’m pleased to say as of 2 days ago I think my dog has turned a corner although it has taken months of hard work to get her there. First of all wash your pet in a degreasing dishwashing liquid, I used fairy. The last few months I have been feeding her a full raw diet and giving her 1 blackmores brand milkthistle tablet. Her diet consists of raw meat, mainly kangaroo but I do switch it up with goat beef and lamb. A little offal. Some sardines. Sweet potato, kale, free range egg and eggshell 2 double strength fish oil capsules and coconut oil. I alternate some of the above. And also some colloidal silver but I think the best thing I have given her is bone broth. Amazing stuff. Last week she still struggled to jump, she could barely make it around the block on her walks and all she did all day was just lay around and not move. She’s still not 100% but 2 days running now she has been on big walks and kept up the pace. I’m over the moon. Also look up the group on Facebook frontline/frontline plus a neuro-toxic poison. There’s a petition on there to get frontline banned. I hope I’ve been some help. If you look up the above group you will see my comments on there. Feel free to message me for any advice I hope your baby recovers

Archan22 Jan 2018Reply

Thanx for the solution.... I bathed my dog and he immediately got up and started acting normally
Before bath my dog was dull, not attentive, muscle twitches, whining, didn't drink water not even a single drop, didn't eat for 18 hrs straight...completely dehydrated,.... Thanx for the solution worked like a charm..... This fipronil should be banned never gonna use it again.... I would rather work more to pick out those ticks than this chemical shit

Fantastic news. I’m glad your dog is on the mend. And yes there is a group that’s working on getting it banned. Hopefully it will happen this year 😊

Donna Brito22 Jan 2018Reply

My dog had frontline 4 days ago, Will a bath with degreaser help her?

Archan kumar22 Jan 2018Reply

I have used this fipronil a few tyms...

From wat i have observed.. after the application..my 🐕 became dull and lethargic ... he didnt respond to anything...
He stays like that untill i give him a bath next day...
I think the chemical irritates his skin or has some adverse nausea like effect on him ..

But when i bath him the next day... his energy comes back and he acts normal again like everyday.. hes only like that untill i bath him...

I just use my regular oat shampoo on him... nothing special to remove all the chemical...

I prefer to sprays his body with fipronil instead of applying that 3 or 5 ml of liquid behind his head... it highly concentration and he didnt like it...

Spraying all over body with diluted one and bathing him next day has done wonders!..

Mel Culph22 Jan 2018Reply

Yes Donna please bath it urgently in a degreasing shampoo or use blue Dawn dishwashing liquid or fairy dish washing liquid. Only use the dishwashing liquid as an emergency. Don’t wash your pets in it any other time. You can also give milk thistle to detox the liver. Good luck I hope it recovers well

I applied the Frontline Plus to my Granddoggie 9 days ago. Yesterday she started presenting with difficulty walking. Today she has to be picked up to go outside to potty. She cannot go up and down any steps. I was glad to find your comments, because I am now almost certain it has made her sick. She also feels very hot and is having rigors We have her on a heating pad and will try bathing her tomorrow.

This is what my Granddoggie is doing!

I applied FrontLine Plus to both my dogs. The following day my 6-year old stopped jumping up on the bed or couch. By that night she was having problems walking. By the time I got her to the vet she was paralyzed. I had no choice but to have her euthanized. This was not the first time I've used FrontLine on them and if I had known about these side effects I would NEVER had subjected my furbies to this poison.

MB23 May 2017Reply

Wash it off with the fairy. Use a flea comb 3 times a day instead. Fill the sink with a bit of water with dish soap in it. Put the fleas/comb into the water when you see them on the comb. Manual works way better than chemical, anyway. Stay on it.

Please everyone as soon as you see symptoms wash your pet in fairy dishwashing liquid or a degreasing dishwashing liquid to remove the frontline from their oil glands. Wash them several times to make sure you get it all off them. There’s some very sad stories above indeed 😭😭😭😭

שמתי אותו על אחד הגורים שלי אחרי שהיא מעוכבת. שיחררתי אותה מאוחר יותר באותו ערב. למחרת בבוקר שמתי לב שגירדה אותה כמו משוגעת. אני צריך לצפות שזה יהיה שכך? אני מודאג כי אני כנראה לא אצליח לתפוס אותה שוב.

קשה לומר כי כל תגובה שונה. אבל אם יש לו תגובה חשוב לא לשים את כל טיפול כימי מבוסס על זה שוב כמו תופעות הלוואי יחמיר עם כל טיפול. אתה צריך לשמור על העין על זה ואם זה נהיה יותר גרוע זה צריך להיות שטף ב degreasing נוזלים לשטוף כדי להסיר אותו בלוטות השמן שלה. מזל טוב וטוב לך על הטיפול xx

Eleanor23 May 2017Reply

Sad stories indeed. I’ve had the same experience with hartguard for heart worms. My little dog began to have seizure-like symptoms which worsened over the months. Finally after the last dose I gave her she couldn’t even stand within two hours. The vet never mentioned it might be the ivermectin. He still refuses to believe that was the cause. After I finally researched the product I found out the truth. All of these products contain neuro toxins that are supposed to kill the parasites and not cross the blood brain barrier of the animal. But with some dogs and especially sickly or old ones, it does! My dog had what they called ataxia. Staggering, shaking, seizure-like symptoms, eyes flitting back and forth rapidly, until finally after the last time we thought we’d have to put her to sleep. But we didn’t, and it took 6 weeks in a dog baby buggy and hand feeding because she was blind and couldn’t hold her jerking head still enough to eat on her own. It ends well though. I quit giving it to her and now I use Wondercide. The one I use has cedar oil and hydrated silica, which is like diatomaceous earth. It kills the fleas! Really. Has to be applied quite often if it’s to repel mosquitos too, but in winter a couple of times a week handles fleas. The fleas just sort of dissolve. The little dog recovered very well after that and loved having the cedar smell on her. Not all of them like it that much but the point is, it will do no harm and it works if you’re willing to go to the trouble. I never want to poison my sweet dogs again, so I do.

I forgot to mention that I have used it on my cat too with success. She’s a rather skittish cat too, but got to where she loved when I’d spray the Wondercide on my hand and rub it all over her. The smell of the cedar didn’t seem to bother her and it didn’t affect her badly in any way. I know cats are different from dogs, but she did fine with it. The only problem is because of the cedar oil, it made her fur clump and I had to brush her frequently to keep that from happening. Go to the product’s website and you’ll find all the info you need. They have products to spray in your house or yard also. Been using it for a year now with success and no more sick animals

Chevy05 Jul 2018Reply

We used Frontline plus on our 3 months old cat, as the instructions stated that it was designed for 2m+ and on our 4y old cat. The 4y old was fine, the kitty became letargic and non-responsive. After the first hour, it stoped moving at all. I searched the internet and found this page with all the symptoms and Mel´s advise to wash the cat several times. My wife washed the cat with soap (Dove), dishwashing liquid and pet´s shampoo. After 1 hour, it opened it´s eyes and we washed again. After a couple hours, it was just a bit letargic and in the next day the kitty was fine.
I belive this product is not safe for younger or older animals, despite what it says in the box/instructions. And I repeat what Mel have said in her post: "as soon as you see symptoms wash your pet". It helps.

I put frontline on my 11 year old cat and couldn't find her for two days. I thought she got outside or something I looked everywhere. She finally came out from where ever she was hiding.

I think I will wash her again tomorrow agter reading these posts🙏🏻She makes it! I have been feeding her with a serynge.

Hi, the vet appled Frontline Spot On (I think it was) to my 4 mth old kitten yesterday afternoon and she's now not herself at all, off food & just lying down looking miserable. I've washed between her shoulder blades where vet applied it. When you say wash the cat, is this sufficient or should I be washing more of her than just the area where it was put on?

Frontline Gold has caused my dog to start having seizures.
Carey - 8 years old - mixed breed - 35 lbs

We applied Frontline Gold for the first time ever to our dog on 01/16/20. Within 5 hours she would randomly scream out in pain/because she was scared and jump into our arms. At the time we thought maybe she hurt her leg or back and would touch her spine, rotate her legs, etc. without finding any indication of soreness anywhere on her body. This would happen sporadically on Friday and Saturday. By Saturday evening, it was happening more frequently. And at this point we realized that our dog was having mild seizures. She was not losing consciousness, but she would cry out/get this look about her and then burrow into us and her whole little body would tense up, she would lick her lips (salivating), and stretch out her neck and put her head high into the air. We took her to the emergency vet and they have since started her on seizure medication and a sedative for now because she is absolutely terrified when one starts to come on. Secondly, she is spending the day at her primary vet receiving fluids and staying under observation - and we will do this again tomorrow. Her behavior is different - she is very clingy - and she has tremors constantly. We feel completely helpless.

Carey was in perfect health prior to application of the Frontline Gold and nothing else has changed in her routine other than that. Frontline refuses to accept ANY responsibility. In fact, when we asked how to get their medication out of her, their only response was to bathe her - which we did 3 times. This medication is so poorly researched that they do not even have a way to reverse it if a dog has a reaction - and that is because according to them, "it is impossible for their product to cause these symptoms."

We are really hoping to wean her off of the seizure meds by the end of the month once the Frontline should be worn off. I really hope she will be able to go back to normal once the poison is out of her body. Frontline should be ashamed of both the fact that they poorly researched this medication/did not provide accurate side effects to the customer, and the fact that they so easily just say it is impossible for their product to cause any of this. DO NOT USE THEIR PRODUCTS. It simply isn’t worth it.

I put frontline plus on my 6 year old cat and soon afterwards she started acting strange like she is having difficultly waling and crying, hiding scratching. It has been 24 hrs and she still seems like she is suffering. I have no idea what to do.

PLEASE read this articular : https://wagwalking.com/condition/pyrethrin-pyrethroid-toxicity It explains what and why and says DO NOT USE ON CATS!!! My dog got ticks on her two days ago and I purchased 'Frontline Plus' for her, to be put on AFTER her bath today. I have NOT had to do this in 4-yrs for her, so I looked up info...DON'T know why companies are changing WHAT DID WORK...you know the saying "If it's NOT broken, DON'T fix it!". I had ALWAYS used 'Frontline Plus' on my other (pass) dogs with NO PROBLEMS EVER! I'm nervos to use this product now...BUT as I have read comments it seems it is the "Frontline GOLD" I should worry about and not the "Plus" product...Here's crossing my fingers and saying a Pray!

I applied frontline plus on my husky. With in an hour or so she started twitching, falling down, unable to move. This has never happened before. I immediately bathed her in dish soap. She is still not able to move her rear legs or even support herself after 4 hours. Very Nother joke

I used this on my 4 month old kitten 6 days ago. He became unwell the day after. He was uncoordinated and extremely lethargic to the point he could barely take himself off to the cat litter. It's taken days but he does seem a little better today thankfully. I will not be using this again!

Hi
I unfortunately used front line on my 5 month old kitten 6 days ago. On 4th day I washed her with fairy liquid. She has not improved nor got worse after bath. Her left side legs and eye are very weak. Cannot walk properly or jump. Is this reversible- Im really worried I cant see any improvement as yet. Although the fits have stopped.

Frances M. French09 Jul 2020Reply

It seems that every time I apply front line to my Westie she looks really unhappy, I'm thinking she is old enough to be showing that she experiences dome adverse reaction mentally. Secondly sphe begins to start itching and losing fur as soon ASD winter comes and the ground freezes, I stop giving front line to her and the itching and hair loss stops. Anyone else see this in their dogs?

I have used Frontline Plus for years with no problem until now. I applied it to my 4-year-old very healthy 14 pound cat in the morning and she was fine all day. In the middle of the night I saw her sitting up on the chest that her bed lies on. She is usually stretched out and sound asleep. I picked her up and put her on her bed and she jumped down and stumbled and had trouble walking. I turned on the light and her eyes looked crazy. I put her in another of her beds and she laid down and stayed there and went to sleep. The next morning she was absolutely back to normal!

This was #2 of a six-pack, so she had gotten the same lot batch the month before. I called the Frontline hotline and was basically told that they knew of no adverse effects except for the foaming at the mouth if they get it on their tongue. Why are all of us having similar issues and yet Frontline doesn't seem to be aware or care??

Does anyone know of any products that are safe and effective?

Thanks!

I used Frontline on one of the feral cats I look after and he isn't eating but wants to. I couldn't wash him but does anyone think that I could maybe throw Fairy washing up liquid mixed with water over him ?

Sam Sallee18 Jul 2020Reply

Decided to try a “different” treatment for our dog and within a couple days, our active dog developed paralysis in rear legs, a couple hot spots on hind quarters, nausea and vomiting, and diarrhea. Vet says “vestibular disease” which is ear issue... I believe the Frontline set off an allergic reaction.

Now three weeks later if providing essentially “hospice care” our dog is walking and eating better. Spirit is improving and although her walk is like a drunken sailor, she is able to get around some. I’m hopefully when the Frontline is worn off, things will be better.

DO NOT USE FRONTLINE. TOO RISKY!!

Also, maybe don’t euthanize if your dog experiences these issues. Maybe a little time and things could improve. I’ve had to euthanize a couple older pets and it’s not easy to do.

This last treatment of Frontline created blisters on the application area by the next morning and stroke-like behavior in my dog within about a week.
I've used Frontline Plus a few times before, purchased from the same store, applied on my same dog, without any issues and I followed the directions exactly as I always have.
For some reason, this last treatment quickly caused a large sore on the application area. I attempted to remove the Frontline with a gentle bath at that point. Within a few days, my dog began losing balance when walking, drooling out of one side, became nauseous after only taking a few bites of food, appeared to be losing site in one eye, and struggled to even get up on the couch.
The vet mentioned other dogs with severe adverse reactions to Frontline in recent months as well and suggested bathing them with dish-soap to remove the application as soon as possible.

Fran23 Jul 2020Reply

We have used this for about 1 yr. My partner really didn’t want to but our cats were flea ridden last year. I have been getting the monthly prescription and applying as per instructions.

The cats vomited more than usual last week but to be honest, I didn’t think it could be the Frontline. I thought it may have been something they ate. However, I have just noticed that one of our beautiful cats has lost a patch of hair and the skin has blistered exactly where that stuff was.

I feel really bad and wished I had listened to my partner.

I put frontline on my rednose pitbull pup that's 8 months old and 60lbs and gave her the rec. dose and I'm just so scared, her eyes are super red but not just that it's her whole body and she's acting weird, like not coming to me when I call her. She got fleas from my moms house being 10mins later she was covered and needed the fleas gone because they were eating her up. Now I'm scared and she is super tired and is asleep now but I can't sleep. I'm going to be a wreck if this gets worse... I tried washing it off 4-5hrs later hopefully that will help.

I have a very active healthy 6 year old Boxer Dalmatian mix. I applied Frontline Gold on him on 06/22/20, by 06/23 he was writhing in pain and his back legs were paralyzed. Because if Covid it was hard to find and emergency hospital open, but I got him into the University of MN Vet hospital. They had to wheel him in on a wagon( weighs 100#) because I couldn’t take him in. They wondered if he had been injured, I said not that I was aware of but I had just applied Frontline to him the day before. They said that wouldn’t cause this. They sent me home with a IVDD diagnosis and a bunch of pain and anti inflammatory drugs and also strict instructions to keep him from climbing stairs or walking too much (his legs were working again). So...I kept him on exercise lockdown for almost a month he has been totally back to normal. I gave him his next application of Frontline yesterday morning and 6 hours later, all this started again. I washed him down with a gentle soap and he is resting now.

I am horrified that vets and vet schools don’t seem to know about this. I feel so bad for those that had their pets put down because of this poison. Believe me, I’ll get the word out!

My cat Maximus is very sick from Frontline. I applied it on a Tuesday and today , which is Thursday I woke up with urine all over the couch. He was vomiting off and on yesterday but figured it was from him always eating fast. Now he is very punky, back legs are not working right, kinda crys when I pick him up as well. He is very clingy.
He has a veterinarian appointment today. I washed the area with Dawn dish soap as was told to do this from the veterinarian. Please keep him in your thoughts. Please beware!

Mel11 באוקטובר 2020Reply

Please wash your pet in a degreasing wash urgently. Use either blue Dawn dishwashing liquid or fairy dishwashing liquid to remove the frontline from their oil glands. It’s very harsh on their skin so don’t use it any other time except in this emergency. There’s several groups on Facebook you can join for more information. Please also report your pets reaction to the manufacturers. They have to record the reaction and the more reports we’ll be closer to get there poisons off the market. Good luck everyone

Applied Frontline Plus to my male silver cat. He has been scratching for days and I looked at where we had applied the Frontline and there is a huge scabby sore there. He is also scratching and biting his skin. I’ve started brushing him and flakes of skin are coming off. Won’t be applying this to him again. I’ve been cleaning the site with coconut oil as I think he will take my fingers off if I gave him a bath. It is 2 weeks since we applied it. Just posting here hoping it will help someone else.

I used Frontline on all 4 of my dogs 4 days ago, that night one of them starting vomiting white foam, the next day she was lethargic. Took her to the vet, X-rays and lab work checked out normal. But she hasn’t eaten or drank anything since then. She was given fluids at the vet yesterday and today. She’s walking around but very slow, drooling and still lethargic. Diarrhea and vomiting still. I’m praying she’s pooping this poison all of her and praying for a full recovery.

I used Front Line on my dog and will never use it again. Within 24 hours he lost the ability to jump up onto the couch or to greet you like he usually does. He was very lethargic.
I’m so glad I found this website, I washed him as soon as I found this information out on here in dish soap and already he seems so much better. He is able to jump up again and is much more lively.
Hoping he continues to make a full recovery.

Kat22 Feb 2021Reply

I put ZoGuard Plus for cats (it has exactly the same percentage of ingredients as Frontline Plus for cats) on my almost 2 year old female cat named Sunny. Maybe 14 hours later, she was lethargic, her eyes looked funny and she was hypersensitive to touch. I just found this blog tonight and so many pets with problems with this flea med. She has had other flea meds with different ingredients and no problems. Tonight she is finally acting somewhat normal, she got up and walked around, watched the goings on outside and her eyes looked mostly normal. She spent several days just sleeping, eating a very small amount of dry food, and not wanting to be disturbed at all. I am hoping that she will be back to normal in the morning (1 am here now). I thought about a bath when she first started looking sick, but she wouldn't even let me pet her for more than 20 seconds. This is normally a very active, very friendly cat, and to see her this way just breaks my heart. I can think of nothing else except the flea med that caused all this. She is indoors only, and there are no toxic products where a cat could get into them. For those who lost their pets to this "medicine", I send my condolences. Hoping to see my Sunny be her usual sunny self very soon. Thanks for listening!

I have a 10 month old Pembroke Welsh Corgi. I quickly noticed he was biting at his legs so I checked him out and sure enough he had fleas. So I took him to PetSmart for a flea shampoo and Frontline Plus for Dogs spot on treatment. The following day he was very lethargic and trembling uncontrollably. He was laying around all day and didn’t seem to have any energy to jump, run and play. I know for a fact he had a horrible reaction to Frontline Plus. I am now bathing him with Dawn dish soap I’m hoping for a speedy recovery!

Did washing with the dawn dish soap improve? I am having the same issue and I am going to get dawn dish soap right now I am so worried...had to bring my girl to the hospital this morning she was barely walking, did not want to eat, I'm so worried.

Kim21 Mar 2021Reply

1 week ago I gave my shitszu frontline, he has licked his belly and legs since then, so much he’s developed a skin rash and smell (I think its yeast) I gave him a bath 2 days after the application (so glad I did ) to relieve his skin with oatmeal shampoo. He’s also been really tired acting, but he is eating. my husband took him to the vet today and vet gave him some prednisone and a CADI injection for the itching. I will not be giving any more frontline. And read an article in USA TODAY about Seresto dog collars being toxic and fatal. So I’m not trusting any of these companies who say flea and tick killer, they are all full of pesticides.

I applied Frontline to my dog about 18 hours ago; he has been up all night crying. My dog is 10 years old and I have been using this product in the spring/summer for many years.
I don’t recall him ever showing adverse side effects.
His breathing is slightly rapid and he just seems generally miserable.

What a nightmare applied frontline combo for cats the fleas started leaping off him almost straight away but the side effects are really bad his whole body is itching hes using his paws to wipe it off then licking so its got into his body running in and out yowling cant keep still i only applied a quarter of the pipette so not alot his inner eyelids are showing i tried to wipe it off with a towel no better so ive used a cloth with Aloe vera fairy liquid on his whole back and hes ran out in the rain hopefully that clears its super concentrated poison that shouldn't be on the market cant use this again they know it does this would of been common in testing but they don't give a fair warning it is misrepresenting a surely dangerous product

I applied Frontline plus to our 15 lb dashound a week ago, and now he's so sick. Hasn't eaten for 2 days, lethargic and acts like he's dying. He's 13 yrs old. Gave him a bath with dawn this am. Worring he will not make it. Plus, he had lots of fleas on this morning's bath!

Anna15 Aug 2021Reply

I'm so grateful I found this blog.
I had used Frontline Kitten on my cat a few times and while he did not like the application part, he seemed to be fine otherwise. I don't think I ever got the full dosage on him though since he is wriggly (probably about half). I waited until he was a year old to give him the adult formula but again - never got the full dosage applied. He didn't show any signs of fleas so I didn't worry too much about that. Yesterday was the first time I'd applied a full dose and I completely regret it. His pupils dilated after and he wouldn't let me pet him at all- just ran and hid. He gets sleepy after vaccines so I wasn't too concerned about it. Left for a few hours and when I went to check on him it was clear he hadn't moved. His eyes were hazy and he wouldn't let me touch him at all (he's normally a total cuddle monster). Called the vet, they said it couldn't possibly be the frontline since its topical and recommended that I continue to monitor him. A few more hours went by - he had barely eaten all day, was still recoiling from my touch and I noticed his third eyelid showing. Found this blog and washed it off. He started purring as soon as I began washing it off- like he knew what the problem was but couldn't tell me. After about 30-40 minutes he let me pet him again and didn't leave my side for the rest of the evening. He seems back to his normal self today and has his appetite back.
I will never use this on him again.

Used Frontline Plus 2 weeks ago, few days later our setter had a very bad stomach and that has continued our other dog a Kortall has now the same problem, the scratching is off the scale and then the licking of the paws which I believer now is transferring this poison into their insides and setting up a viscious circle, I have bathed them and will bath again tomorrow, the setter is more lethargic than normal too and has a very dry nose, they seem to be eating normally, but we are at our wits end, have been using this stuff for years now and never had a problem, so what has changed in it? also ten years ago we used Advantage on one dog and she nearly died, developed diabetes withing 24 hours of putting that on her, and then she suffered 2 years of illness, found out after there were court cases in america over that product, and lots of dogs had either died or been severely injured..that is why we decided on frontline plus and had no trouble until now..am so angry, our babies are suffering, how can this product be allowed if its causing this many problems, glad I found this site..I will not be using this stuff ever again its poison...does not even get rid of fleas...but seemingly is getting rid of our pets...this company needs looking into..

My poor 15 year old cat died the day after I applied Frontline to the back of his neck and I now have to live with the fact that I killed him. Since then I've not used the product on the others as I'm so nervous. It is definitely a risk that I may have to take again though, sadly.

Dealing with this issue with my 9 yrs old pup. Been on frontline plus for years, but this round seems to have been the issue. Gave 3 weeks ago, and this week and last he is exhibiting all of these symptoms, random whining, dazed, slow wandering walk, no stairs or jumping, itching, barely eating. Been to vet twice, all checks out fine, no solution. They started him on antibiotics today for possible inner ear issue, but now I see this thread and realize it was frontline and his age now causing issue. Just bathed him in dish soap, don't have dawn tonight so used what I had, likely again tomorrow, hoping I can get it off glands after weeks and this gets out of his blood stream. Thank you for your stories.

My car 11 year was acting lethargic , weak little pained meow , not eating , acting confused very worried took to vet … $768 later , bloodwork , X-rays normal then I had a revelation about giving him frontline plus 3 days prior . My cats had always tolerated , not sure if he was able to lick some off this time .. still waiting to see if he recovers . If I had known this I would never had used , and my vet never mentioned anything when I asked about possible poison .
I will mention when I speak with her tomorrow . I think they don’t believe in these reactions as they encourage them , just as small # people with vaccine injury are dismissed because most people do fine .

I know it's been a while since anyone has posted but my 1 year old Husky started having extreme skin issues, pain, and a gross open wound right where I put the frontline about a week and half after I applied it. Now 2 days later his hind legs are walking really strange, he is breathing so fast, and he is extremely lethargic, and depressed. My normally energetic dog is just laying around all day and has no interest in playing. I'm so concerned for him. I'll do the fairy wash right away, but I'm freaking out for him. Any suggestions of what else helped and how long it took for your sweet pets to get better?

My dog Jack is a 13 year old Porkie (Pomeranian + Yorkie). He has an enlarged heart and some slight kidney issues due to age and is taking meds daily for those issues. He is however, still very active and a happy little dog. On 03/19/2022, I gave him Frontline Plus exactly as instructed. Applied one dose on his skin on his shoulder blades. Exactly 24 hours later, on 03/20/2022, we woke up and my dog was very weak and couldn't get up. I put his harness on him and tried to take him for a walk but he fell on his side. That's when I realized that he has coordination issues as well. Took to vet and he tested everything from heart, to kidneys, blood, etc - and after a $1080 bill, vet couldn't find any issues (all his pre-existing health issues were same - no change). That's when I realized this could be from the Frontline Plus. Came online and found this blog. For 9 days - from Sunday, 03/20th to Tuesday 03/29th, he went through hell - coordination issues - mainly stumbling when walking and severe depression. He would walk like a zombie as he looked like he was sleep walking and even then stumbling and almost falling over. Giving him his food + meds for his heart was a nightmare. The saddest was the severe depression.
However, he seemed like he was about 90% better on day 9 (03/29/2022). By day 10 (03/30/2022), I could say he was all good. I gave this timeline so that anyone who has a dog going through issues due to Frontline crap can see that there is hope. Jack came out of the hell he was in and hopefully your dog will too. The vet was of no help and didn't say much even when I mentioned that I found so many people online who are complaining about Frontline plus. I guess there's nothing much vet could do when it's neurological issues.

I will never use Frontline on my cats ever again. I bought an application from our vet for my cat a few years ago. The next day he had a bald spot on the back of his neck & started walking differently and scratching himself there horribly. I took him into the vet right away & they suggested a sweater for him to keep him from scratching the area, I kid you not! He began losing his ability to walk & the vet assured me his medication had nothing to do with it. Within days he passed away. Never again!

All I can say is after administering the right amount in the right place on my 40kg 7 month old pup he was looking at me as if I wasn't there not acknowledging me panting like mad then lying on the floor couldn't even hear him breathing I had to check a few times if he was, luckily he was as a large breed he doesn't normally breath quietly while sleeping, it was as if his whole personality had gone in the space of 5 minutes. The best way I can describe it is with Harry Potter it was as if all the joy had gone from him and like a dementor had sucked the life out of him without a doubt scariest hour ever. I decided I would wash it off and if he was no better run him to dog A&E luckily after I showered him within 5mins he was back to his normal bouncy cheeky self my only advice is to not use this product and if your dog reacts this way wash it off.

I applied it to my dog yesterday. He already had terrible skin condition all over his body and we don’t know what it is so we were hoping this would help. He threw up twice and was foaming at the mouth a little. He is acting fine but he also is bleeding on his head where his skin was really bad and patching and it looks scary. I administered the correct dosage and don’t think he injected it but maybe he scratched his back where I applied it and then licked his paws

So..... I have used frontline for years on my 2 dogs without a problem. Rescued a puppy Karakachan this June who had been tied on the common and left to die. Put Frontline on them all 2 days ago and since then the pup has become more and more lethargic, and even lost his appetitie, vomiting and diarrhoea. Will try the bathing thing and see what happens. Feel guilty as all hell for putting this on him. Seems he may be super allergic to this stuff.... Going to try the old Bulgarian trick of garlic water in future. Anything has got to be better that putting my little man through this..... and myself!

Frontline plus - Dog seizures

I put frontline on my 13 year old mini schnauzer, within 4 hours he had a seizure. He then went on to have two more in the next 24 hours. I’m convinced it was down to this flea and tick treatment. Fingers crossed it’s now two days later and no more seizures, but he still isn’t himself and won’t jump up on to the sofa. I thought this was a weird symptom, but having seen the comments, apparently quite common.

This stuff should not be on the market. Applied to my 14 year old dog. First thing was throwing up and diarrhea. She has had 3 major seizures in a week. Applied about 2 weeks ago and hoping this wears off. I am heart broken for our sweet little dog.

We put frontline on our dog last December and she started having seizures just a couple of days later. Have your dog’s seizures subsided?

So we got a sweet little cat from a man who was dying a few weeks.ago. we put Frontline on him right way and he start acting like he was very tired and won't move. We though since it was his first week away from his owner. It might be that. Until we reapplied it yesterday and he is doing the same thing exactly with a fever. It is like a complete repeat of last month. No more Frontline here. 335612

My cat died after we used front line plus. We put it on, he went out, next morning he was dead in my front garden. He was only 7 years old. Devastated.

Has anyone experienced their cats having a very bad reaction after applying Frontline spoton.
Over grooming, itching, biting and scratching for over a month after the application.
